A rectangular pool is 20 feet wide and 50 feet long. A deck used for sunning surrounds the pool. The deck is the same width all the way around the pool. The total area of the deck is 456 square feet. How wide is the walkway?A. 2 feet
B. 3 feet
C. 4 feet
D. 5 feet

Answers

Ahh, this question goes all the way back to my year 9 test a couple years ago; which I got wrong back then - I now know how

Firstly we find the expression for the area (using x as the walk way):
>50x * 2 (the left and right)
>20x * 2 (the top and bottom)
>4 * x^2 (the corners)

Add them all together , Area = 140x + 4x^2
Now we place the deck's area, 456 into the expression

456 = 140x + 4x^2

Solve for x
I'm a bit rusty on this i'm afraid, but I believe the only way to solve this is to factorise it
0 = 4x^2 + 140x - 456
0 = 4(x+38)(x-3) <
x must = -38 or = +3 (the numbers inside the brackets inverted)
x must = +3 as it's logical, you can't have a negative width

The walkway is 3 feet wide, we can put this into our expression to double check this,
456 = 140*(3) + 4(3)^2
456 = 420 + 4*9
456 = 420 + 36
456 = 456
Yes, 3 feet wide is correct.

*Note, I tried to keep this simple, please let me know if I didn't go into enough detail anywhere

Anyone with a Social Security number is a possible victim of identity theft. Specialists believe that early identity theft awareness will considerably reduce the harm caused by theft.

Answers

for number 1, you divide both sides by -3 and because it is a negative number, you need to flip the sign so the answer is d.
For number 2, because you need to make the x by itself, you multiply both sides by 5 which gives you c.
For number 3, you add both sides by 4 so you get a.
For number 4, you find the number between -5 and 0 so the answer is c.
For number 5, the answer is b. nothing much to explain.
For number 6, its the greater than with the line underneath
For number 7, the answer is d.
For number 8, b

Anna earns $12 in 3 hours. How much does she make in 5 hours?and please explain,asap I have a test on this tomorrow!

Answers

20 dollars in 5 hours

if she earns $12 in 3 hours we need to find out how much she makes in 1 hour.

To do that we divide the total money by the hours 12/3 = $4 per hour

Then we multiply the number of hours times the per hour rate: 5 * $4 = $20

Anna will make $20 in 5 hours
